Thinking of a completely different approach:- See the gold spring contacts on the Keithley 480 Picoammeter at 27:20 of Dave Jones video: kzread.info/dash/bejne/rHiXzpJmpJrJlbw.html Shouldn't be too hard to find some suitable springy material, and get it gold plated, then operate the springs by plastic rods driven remotely by small cheap solenoids. ?

This is great video! I've been using Monport Laser for several months now, and I've been amazed by its versatility. While MOPA Fiber Laser Engravers can handle a range of tasks like welding, cutting, cleaning, and coloring, Monport Laser takes it a step further. With Monport Laser, I've been able to tackle not just engraving, but also precise milling tasks with ease. Its intuitive interface and robust performance make it a standout choice for various applications. Whether you're working on intricate designs or heavy-duty projects, Monport Laser delivers exceptional results every time.

Very nice work. My only comment is that 30% Z load at idle isn't really that bad. You don't want it fully balanced, and having the weight of the Z-axis help in plunging loads is helpful.

Neat stuff. I think all cars have switched to clock spring style connections to the steering wheel. What about a motorized rack to engage the connectors? That way they wouldn't drag and they wouldn't connect until positioned. I agree with other here that a pair of contacts at the end of travel for homing would be better. Or if you go with lifting the wipers like I mentioned you could use something like pogo pins for the end indication.

Try soldering reed contacts radialy and a glue a piece of magnet on cursor then fly it over desired reed contact with the steper ... no heat there no oxidation, maybe is what you need!? (you can use existing pcb if you find reed's small enough)

Slip rings in steering wheels are basically not a thing anymore, they use a winding spring flex pcb cable to allow for ~3-5 turns in each direction. Before airbags were a thing that was different of course. German word is: Wickelfeder Spiralkabel btw.

@marek_ryn5 күн бұрын
Other idea: Put magnet on that wiper and it will move over small levers that will close contacts. Wiper can be on threaded stud and move linearly. Levers must be plastic with small metal part to attract magnet. With smart mechanism you can even omit unintended connections and only lower magnet over the required contacts.

Maybe don't use rotary switches, but linear ones and use off the shelf carbon brushes with spring brush holders? Might need some maintenance but seems a more sensible design for DIY?

You could deal with the potential of shorting intermediate configurations while turning if you made one switch that turned all of the front panel connections on and off at once. A modified version of your rotary switch, with individual input and output pads, then a stepper motor with a multiple-wiper fixture on it, to open or close all of the front panel contacts at once...

I don't know why you're doing all this with those mechanical switches. It's too nerdly for me to care about learning! HAHA! 🤣🤣 However, I do know that you're trying to avoid mechanical wear. As I was watching I got an idea. Why not use pools of liquid mercury for one side of the contact points? This would never wear out of course but it would be extremely annoying to maintain. Every time you moved it you'd have to worry about the mercury spilling everywhere. Also, the wiper metal would have problems with amalgamation issues. So then, I thought about the same but with something like galium. It could be a solid and then could be easily heated up when in use. The problem here though is in the summertime it would get too hot and you'd have the potential for the gallium to leak everywhere when moved. So this directed me to think about the same but with fusible alloys. Say, Cerrolow 136 for example. It's an alloy that melts at 136 degrees F and is made up of bismuth 49%, lead 18%, tin 12%, and indium 21%. No cadmium so it's safe to use. Kind of expensive cuz of the indium. Anyway, you could use it in its molten state by keeping it molten while in use, or it could be used in its solid state and then heated periodically to restore the wear created by the wiper.

As fot the homing; the bump stop really doesnt need to hit the delicate flexible part of the wiper. Making the wiper arm in to a T shape and bumping with the other side for example.

One position end stop sensing trick from the entertainment moving light world that is all stepper driven is the edge sense the stop contact and calculate the center. The motor drives in one direction until it sees the stop contact or optical gate, then continues past the contact until it sees the other edge. The microprocessor then calculates the number of steps between those two changes in state and sets that as the "home" position.

Slip rings in steering wheels? Just about every steering wheel I've had to pull used a clock-spring style ribbon cable. (note: central US here) +1 for an optical endstop, or consider the bolt on servo controller for the nema steppers. the addon is pricier, but with the added benefit of having the motor driver built-in instead of needing a seperate driver board. just a thought.
